Question

I have some anonymous branches in dev named branch that eventually will be merged into default branch. How do I find the latest changeset of dev branch that was already merged into default branch?

This is what I came up:

1. I started by showing all the merges in default branch:

   merge() and branch(default)
   

2. What I really want is their parents in dev branch:

   parents(merge() and branch(default)) and branch(dev)
   

3. That gives me all the dev changesets that were merged into default branch. Now I just add max to get the latest one. This is the final expression:

   max(parents(merge() and branch(default)) and branch(dev))
   

The problem is that I think that this query is too big. Is it possible to get this information with a simpler query?

Answer 1

I think that this will do it:

max(p2(branch(default)) & branch(dev))

It gets the changesets on dev that are the second parent of a changeset on the default branch and the max gets the latest one.

It’s only one condition shorter though (because the p2 condition effectively combines the parent and merge of your query because you can’t be the second parent if you’re not a merge).
